Application led March 24, 1921i. Serial No. 701,395.

The present invention relates to a mixing apparatus for use in connection with the re-` l)Lining of oils, and particularly light mineral oils such as kerosene, gasoline and like distBhe line 7, which is 'indicated by arrows in i0'. l. with a chamber 9, provided at one end with a perforation th-rough its wall, this perfora- The dispersing device is formed 6 tillat'e products.

from the following description, illustrated by the accompanying drawings, in which:

' Figure lis a View, partly in section, showing apparatus constructed in accordance 1 0 with the invention; and

Fig. 2 is a sectional vienT through the disn tributing device shown in Fig. 1.

' In many cases, in the treating of light mineral oil it'has been found advantageous .to employ relativelyminute amountsof au immiscible or partly miscible treating reagent; for'example, in proportions of one to two pounds of treating reagent per barrel of the liquid treated. The proper admixture of the liquid to be treated with such minute amounts of the treatingl reagent has been found very difficult, inasmuch as the treatf ing -re."1.g ent tends to react with a small pro- .portion of the oil, the particles of the treatying reagent becoming coated with reaction products and lea-ving the greater portion ofthe liquid untreated; By means of the apparatus [of this invention, a thorough, intimate homogeneous admixture of minute amounts of the treating reagent may be effected, thus producing launiform and adequate treatment of the entire batch.

Referring more particularly to the drawings, the numeral 5 indicates a conduit through which the liquid to be treated passes, this conduit being provided with a vsuitable valve 6, shown partly broken away'.

From the line 5, on one side of the valve 6, a line 7 is brought around .to the other side .'of the valve 6, this line 7 hereinafter designated the mixingconduit, being provided With-a control valve 8. 4Beyond'the connecf tionof the mixing conduit 7 with the line 5 y there are provided in the latter a number of orifice plates 8*, this portion of the line 5 operating as an orifice mixer. v

Within the mixing conduit 7, before '1t connects with vthe line 5, there is provided a dispersing device shown in side elevationlin Fig'. 1 and in section in Fig.. 2.' This dispersing device is so'constructed as -to finely atomize the treating reagent and distribute it in' a direction substantially transverse to the movement ofl the oilpassing through the chamber 9. A threaded valve stem 13 is connected to the valve member 11 and extends through a threaded opening in the Opposite -end 14 of lthe 'chamber 9. The valve stem extends through thewall ofthe conduit 7fand is provided externally thereof D- with a suitable valve head 15, by rotation of which the valve portion-11 and with it the external conical portion 12 may be moved inwardly or outwardly to enlarge or decrease the size of the opening 10. A supply pipe 16 for the treating reagent .passes through r the wall -of the conduit 7 and communicates with the interior of the chamber 9.

In operation the' liquid to be treated is l caused to flow through 'the mixing conduit 7 by closing the valve 6 and opening the valve 8. The treating reagent is forced into the conduit through Vthe pipe 16, enteringV I `the chamber 9 and being atomiied in its passage through the openingy 10, the effective size of which is controlled yby the valve 1 me1nber 11. The atomized and finely dispersed ltreating reagent is then forced outwardly transverse to the currenttof the liquid flowing through the mixing conduitby the action of thereverse conical element 12, which may, if desired, be provided at its en'd withan outwardly extending flange 20. The proportion of treating reagent 1s controlled by suitable manipulation of the lvalve l5, and an intimate and uniform 'admixture vof ythe treatingy reagent with the liquid is thereby' produced. The mixture of liquid and treating reagent is caused to return to the conduit 5 and is forced through the ori-l ce plates 8a, lthe mixing operation thereby continued.

-Ve claim: v

being' 1. In a mixing device, a conduit through which material to be treated flows,"a hollow head withinsaid conduit having an opening directed in 'the direction o fiiowof liquid through vtle conduit, a valve member within said head for controlling the 4size ofthe direction of How of material passing through said opening and means for supplying a treating reagent to theinterior of said head.

2. In apparatusfor mixing minute quan tities of a treating reagent With a liquid to be treated, a conduit through which thel liquid to be treated flows, a mixing head Within Asaid conduit, said head having `an opening directed in the direction of-tlow of the liquid, a conical valve member *Within said. head for controlling the size of the opening and a reverse conical vmember ex-4 teriorly of the opening and connected to the conical valve member for 'controlling the direction'of flow of liquid leaving the head, and means for introducing a treating reagent int-o said head. t

3. In apparatus for mixing minute quantities of a treating reagent with a liquid to be treated, a conduit through which the liquid to be treated flows, a head Within said conduit andhaving an opening directed in the direction of flow of liquid to be treated, a conical valve member Within vsaid head for controlling the effective size of the opening; a reverse conical valve member within saidJ `head for controlling the admixive sizeof the opening, a reverse conical member exteriorly of they head and connected to the conical valve member, said reverse conical member having an outwardly' directed fiange at its outer' end, and means for introducing 'the treating reagent into said mixing head. l

4./ An apparatus for mixing minute quantities of a treating liquid with a liquid to be adjusting said valve, spreading means adjacent to said opening and Without vsaid head `for the purpose of directing the treating liquid substantially across the ow of the liquid under treatment, and means extending through the Wall of said conduit for Y supplying liquid reagent to said head.
